2 Claims.

This invention relates to new and useful improvements in electric condensers and more particularly to a liquid insulated condenser Ifor battery or magneto ignition.

Present day condensers are being constructed in such a manner that regardless of how well insulated internally, said insulation is insufficient to keep out moisture which is detrimental to all condensers. Furthermore, all condensers expel air when engine heat warms said unit, and take in air, most of which contains moisture, when engine is stopped and allowed to cool.

It is the primary feature of this invention to provide a condenser that will prevent air from entering within the condenser walls by being submerged in insulating liquid carried by a cylinder in which the condenser is held.

Another important feature of this invention is to provide a cylinder holding said condenser and a non-conductive insulating liquid within the cylinder.

A further feature of the present invention is to provide a condenser of the character referred to that is particularl well adapted for use in motor vehicles.

A still further feature of the present invention is to provide a condenser that is strong and durable in construction, eflicient and reliable in operation, relatively inexpensive to manufacture, and otherwise well adapted for the purposes for which the same is intended. I

Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein like numerals refer to like parts throughout, and in which:

Figure 1 is a vertical sectional view of the improved condenser with parts broken away and shown in section;

Figure 2 is a top plan view thereof the cover removed therefrom, and

Figure 3 is a top plan view of Figure 1 the lead wire removed therefrom.

Referring now to the drawings in detail, wherein for the purpose of illustration, I have disclosed a preferred embodiment of the present invention, the numeral 5 designates an outer metallic tubular casing open at its top and externally threaded at its upper edge 6 to receive a cover 1 having internal threads 8 adapted to engage the thread at the upper edge 6.

Suitably secured at 9 to one side of casing 5 is the curved inner end ill of a horizontally positioned bracket ll having an opening Ila in its outer end adapted to receive fastening means for securing the cylinder to a supporting surface in a vertical position.

Forming an integral part of cover 1 and projecting upwardly from the center of said cover is an externally threaded boss l2 adapted to receive an internally threaded preferably hexagonal packing nut l3.

A vertical bore It extends through nut 83, boss I! and into the casing, said bore adapted to receive the lead wires l5 from a condenser l6 loosely carried within the casing.

Packing material I! is compressed by nut i3 around the insulating lead wires l5 thereby preventing leakage of the non-conductive insulating liquid l8 within casing 5 in which condenser I6 is submerged.

A ground wire i9 is removably connected at one end to the inner face of casing 5 adiacent its top and the opposite end of said wire is con 'nected to the condenser.

A gasket 20 is preferably carried by the upper edge of casing 5 b cover 1.

In this manner the casing 5 is air and leak proof and conveniently holds the insulating liquid.

The condenser l6 being completely submerbed in said liquid no moisture can enter the condenser thereby greatly adding to the life and efficiency of the condenser.

For the purpose of connecting the condenser to a battery or the like (not shown) lead wire I5 is provided at its outer end with a substantially U-shaped connector clip 2|.

In view of the foregoin description taken in conjunction with the accompanying drawings it is believed that a clear understanding of the device will be quite apparent to those skilled in this art. A more detailed description is accordingly deemed unnecessary.

It is to be understood, however, that even though there is herein shown and descirbed a preferred embodiment of the invention the same is susceptible to certain changes fully comprehended by the spirit of the invention as herein described and the scope of the appended claims.

I claim:

1. In an electrical apparatus, a casing provided with a removable cover at its upper end, a sealing member interposed between the casing upper end and said cover, a boss integral with said cover and having an aperture therein, a sloping upper surface on said boss, a usual condenser held within said casing and submerged in a non-conductive insulating liquid carried by the casing, a lead wire connected at one end to the condenser, the opposite end of said lead wire extending through said boss, means carried by said boss around the lead wire adapted to prevent leakage of the insulating liquid from said casing, said means including a cap having a gasket therein, said gasket being seated on said sloping surface, a ground wire connecting said casing to said condenser, andymeans secured to said casing for securing the casing to a'support surface in a vertical position.

2. The combination of claim 1 and slopingsurfaces in said cap for constantly urging said gasket against said lead wire.
